## Summary
OpenBSD 8.0 has been released with several notable hardware and virtualization improvements. The BSD operating system now supports virtual machines with up to 64 virtual CPUs, a significant increase in scalability for server and cloud deployments. The release also introduces Intel Arc graphics support through updated DRM drivers, expanding the range of modern Intel GPUs usable on the platform.

Additionally, OpenBSD 8.0 adds hibernation support for ARM64 architectures, addressing power management needs on that growing server and embedded platform. The updated DRM drivers suggest broader compatibility with contemporary display hardware. These changes follow OpenBSD's continued focus on security-conscious infrastructure while gradually expanding hardware support for production workloads.

## Virtualization, graphics, and ARM64 changes in OpenBSD 8.0
- **64-vCPU VM support:** The hypervisor and scheduler have been extended to allow guest virtual machines with up to 64 virtual CPUs, increasing density for server virtualization workloads.
- **Intel Arc graphics:** New or updated DRM (Direct Rendering Manager) drivers enable support for Intel's Arc discrete GPU lineup, which previously lacked OpenBSD support.
- **ARM64 hibernation:** Power management infrastructure on the ARM64 architecture now supports system hibernation (suspend-to-disk), matching capabilities already present on x86 platforms.
- **DRM driver updates:** The broader DRM subsystem refresh implies additional hardware compatibility fixes and potentially newer kernel graphics interfaces for supported GPUs.

## Why it matters
The 64-vCPU limit brings OpenBSD's virtualization closer to Linux KVM and FreeBSD bhyve capabilities, making it more viable for hosting providers running security-focused guests. Intel Arc support reduces a graphics hardware gap that has pushed desktop users toward Linux or proprietary systems, while ARM64 hibernation strengthens OpenBSD's position in edge and low-power server deployments where that architecture is gaining share.
